To fr/ZZ zf-wm it 11u01/ concern:

Be it known that I, J osEPH BRooMn, a subject of the King of Great Britain, and a resident of Bayonne, in the county of Hudson and State of New Jersey, have invented a certain new and useful Chimney, of which the following is a specification.

This invention relates to chimneys com posed of a core of masonry, brick, iron, steel, or other material reinforced by a steel or iron structure on the outside and inside.

I` he organization of the invention is characterized by a chimney with the usual inner lining of fire-brick and the like, all of which is supported by a combination of trusses that supports different sections of the chimney proper in both vertical and horizontal directions, thereby allowing the walls of the said chimney to be light and thin. Sections of the chimney can be removed without interference with other portions thereof, and fines can be inserted through its walls to connect with the main iiue without endangering its strength or stability. Oirculating air-ducts are formed between the outer wall and the lining, allowing the induction of air from the outside to the main ue.

Referring to the drawings, Figure 1 shows an elevation of a chimney embodying the invention. Fig. 2. represents a vertical axial section of Fig. l. Fig. 3 is a partially-enlarged section of Fig. 2 on the line ma'. Fig. a represents a fragmentary portion of Fig. 2. Fig. 5 is a partial top view of Fig. 4. Fig. 6 is an enlarged fragmentary view of the upper portion of Fig. 2. Fig. is a view similar to Fig. et somewhat modified. Fig. 8 is a partial top view of Fig. 7. Fig. 9 shows a partial end view of Fig. 8. Fig. 10 is a view similar to Fig. 4L with a still further modification. Fig. l1 shows a partial section of Fig. l0 on the line rv fri.

An inclined core or outer wall of masonry or brick is shown at A, on the inside of which is located thelining or fire-brick wall B, forming an annular air-space A between them. A foundation D below the wall A and lining B supports the lower section of the chimney. Around the outer wall A there are located the vertical trusses O, consisting of the chords O U, connected by the inclined members O:s O". The trusses O are connected by the braces O and the inclined members OG. At the lower portions of the outer chords O of the said trusses are secured the cover-plates O7, which latter are connected to the angleirons O8, that form the feet for the trusses O and by means of which they are secured with the plates O to the foundation-stones D.

Embedded in the lining B are the angular rings E,'to which are secured the angle-irons F, that in turn have between them and secured thereto the gusset-plates G, which latter are fastened to and between the chords of the trusses O.

In the outer wall A is embedded the channel-iron ring H, which is reinforced by the angle-iron ring H, and the angle-clips H2, fastened to the said gusset-plates G, form a support for both the rings H and H. The combination of the plate Or with its appurtenances constitute a bracket which I will designate with the letter I. A number of such brackets, with their rings, Sac., are fastened to the trusses O at dierent levels, supporting the chimney in sections.

At the upper end of each pair of chords O O2 there is formed a bracket I, consisting of the gusset-plate Or, to which is fastened the angular ring E by means of the angle-clips F. The said gusset-plate G also carries the I-beam rings J by means of the angle-clips K and K.

Extending from the chimney are shown the flues L. In the outer wall of the chimney are formed the openings b and through the inner lining the openings b, forming ducts through the annular space A from the outside to the inside of the fine A2.

In Figs. 7 to 9 the invention is modified by eliminating the angular rings E and substituting arches B, built in the lining B2, as shown, and which are supported on inclined shoes or supports O, extending from the gussets G2 of the brackets, that are carried by the trusses O.

A further modification is shown in Figs. 10 and l1, where the inner lining or fire-brick is represented at B3, having embedded therein the angle E2, supported by a gusset Or", fastened between the chords O10 O11 of the girders surrounding the chimney. Instead of an outer wall of masonry or brick fianged sections II, of iron or steel, are bolted together and to the gusset-plate G3. i

Having described my invention, I claiml. The combination in a chimney of sections trusses around the chimney, means between each section and the trusses to support each 'section independently of any other section of the chimney.

2. The combination in a chimney of secthe said ring's, a iue extending through the walls of the chimney connecting with the main Hue thereof.

5. In a chimney the combination ot' sections in the walls and liningI thereof, trusses on the outside of the chimney and surrounding the same, brackets extending from the trusses and supporting the said sections, l'lues in the walls of the chimney connecting with the main Hue of the chimney.

6. In a chimney the combination of sections in the walls and lining thereof, arches in the lining between the different sections, trusses on the outside of the chimney and surrounding the same, brackets extending from the trusses supporting the sections of the walls and the arches of the lining'.

7. In a chimney the combination of sections in the walls and lining thereof, air-ducts from the outside to the inside of the chimney, trusses surrounding the walls of the chimney, braces connecting the trusses and brackets eX- tending from the trusses supporting the said sections.

8. In a chimney the combination of an outer wall in sections, a lining within the outer wall in sections, trusses surrounding the outer walls, gusset-plates extending from the trusses and means between the gusset-plates and thc sections to support the latter.

Signed at New York, in the county ot' New York and State ot' New York, this 24th day ot' September, A. D. 1904.
